CVE-2026-41986

Physical service interruption via filesystem logic bypass

Published Jun 9, 2026 · Updated Jun 9, 2026

Logic bypass in the Huawei HarmonyOS file system 5.1.0, 6.0.0, and 6.1.0 allows physically proximate attackers to interrupt service. Huawei has not published the affected file-system routine, the attacker-controlled input, or how loop-condition input escapes validation. Exploitation requires physical access and no privileges or user interaction; Huawei reports only an availability impact.
